Richard Giroux Posted December 14, 2019 Share Posted December 14, 2019 I had these two Atari's connected some months ago. Had to put them away now I can't seem to get a display. I get this...flickering RED. Pretty much the same display on ch2,3 and composite. What am I doing wrong? Quote Link to comment Share on other sites More sharing options...
griff3125 Posted December 14, 2019 Share Posted December 14, 2019 Odd that they are both doing the same thing, can you try a different switchbox or rf adapter? And it's doing the same with the Din-5 Composite cable? Did you try switching the power supplies around on the two units? Maddening to say the least, good luck!

Richard Giroux Posted December 14, 2019 Author Share Posted December 14, 2019 Two different power supplies Multiple video cables 3 TVs 2 different computers (Full "working" 800xl, XL with failed memory - still used to display memory test) Quote Link to comment Share on other sites More sharing options...
xrbrevin Posted December 14, 2019 Share Posted December 14, 2019 reddy brown screen has implications for MMU, RAM or OS ROM but for it to happen both machines is a bit unlikely to say the least..! Quote Link to comment Share on other sites More sharing options...
Mclaneinc Posted December 14, 2019 Share Posted December 14, 2019 (edited) Any chance there was any moisture where they were stored? Are you aware of the ingot PSU, its got a tapered look, could you have used this to test both machines if you have one of these PSU's? They are known machine killers..If you used it (if you have one) to test both machines then it won't matter what other PSU you try after...

griff3125 Posted December 15, 2019 Share Posted December 15, 2019 Just curious.....is it able to boot a disk or a cartridge? Any sounds? Quote Link to comment Share on other sites More sharing options...
Colleton Posted December 15, 2019 Share Posted December 15, 2019 If you have a voltmeter check the voltages on both PSUs. Maybe one of the PSUs is bad (over voltage) and blew both machines before you tried the other PSU? Quote Link to comment Share on other sites More sharing options...
